Optimistic mode

If a property works in optimistic mode (when the corresponding state topic is not set), Home Assistant will assume that any state changes published to the command topics did work and change the internal state of the entity immediately after publishing to the command topic. If it does not work in optimistic mode, the internal state of the entity is only updated when the requested update is confirmed by the device through the state topic.

Using Templates

For all *_state_topics, a template can be specified that will be used to render the incoming payloads on these topics. Also, a default template that applies to all state topis can be specified as value_template. This can be useful if you received payloads are e.g., in JSON format. Since in JSON, a quoted string (e.g., "foo") is just a string, this can also be used for unquoting.

Say you receive the operation mode "auto" via your mode_state_topic, but the mode is actually called just auto, here’s what you could do:
